What is CCS

CCS (Carbon dioxide Capture and Storage) is a technology to separate and capture CO₂ from gases emitted by factories and power plants and to store it safely deep underground.

Initiatives Toward Practical Application

This technology is effective in reducing CO₂ emissions in Hard-to-abate sector and plays an important role in building a sustainable future. For practical application, it is necessary to establish surveys of strata suitable for CO₂ injection, wells for injection, and technologies and know-how for long-term and stable storage.

The Three Steps of CCS

①Separation and Capture of CO₂
CO₂ is separated from flue gas generated at power plants and large factories and recovered as high-purity CO₂.

②Transportation of CO₂
Separated and captured CO₂ is transported to the storage site. Various modes of transport exist, but for large-scale transport, pipelines or ships are used.

③Injection and Storage of CO₂
CO₂ is injected and stored underground through wells drilled deep into the subsurface, and monitoring is conducted to ensure it remains stably underground. Advanced and wide-ranging technologies are required, including technologies to identify suitable storage sites, drill wells, and understand storage conditions.

By leveraging technologies and expertise cultivated in oil and natural gas development and in the gas pipeline business, JAPEX contributes to the CCS business, particularly in transportation as well as injection and storage technologies.

Moves Toward the Practical Application of CCS in Japan

In Japan, the "Long-term Roadmap for CCS" was compiled in 2023, and in 2024, the "Act on Carbon Dioxide Storage Business" (commonly known as the CCS Business Act) was enacted, steadily advancing efforts toward the practical application of CCS.

In 2023, Japan Organization for Metals and Energy Security (JOGMEC) began soliciting applications for the "Advanced CCS Projects," which provide integrated support for the CO₂ value chain from separation and capture to transportation and storage, marking the start of robust government support for CCS projects. In 2024, two domestic projects in which JAPEX is involved--Tomakomai in Hokkaido and Higashi-Niigata in Niigata Prefecture--and one overseas project involving storage in Sarawak, Malaysia were selected.

Through these three Advanced CCS Projects, JAPEX promotes the practical application of CCS.
